摘要：

A nanocomposite Al2O3/Al material has been prepared by consolidation of nanocrystalline aluminum particles which have been passivated with an alumina overlayer prior to the compaction step. Nanostructured Al has been prepared by the gas phase condensation method. The material has been characterized by XPS (X-ray photoelectron spectroscopy), DSC (differential scanning calorimetry), TEM (transmission electron microscopy) and AFM (atomic force microscopy). This study allowed us to demonstrate that the consolidated Al2O3/Al material, although showing a metallic shine and an ohmic electrical resistivity, presents a microstructure constituted by Al grains interconnected by a very thin alumina network, which prevents the material from falling apart when heated at temperatures above the melting point of aluminum.
